STO P-VALV E.

SPECIFICATION forming part of Letters Patent N0. 360,290, dated lvIZll'Ch 29, 1887.

(No model.)

To all whom it may concern.-

Be it known that l, DUSTIN GlLsoN, a citizen of the United States, residing at Burlington, in the county of Des Moines, State of Iowa, have invented certain new and useful Improvements in Stop-Valves, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improved valve and disehargespout for sand-towers, 8:0. The object I have in View is to so construct and arrange such valves that they will be less liable to wear; and as regards the spout my object is to so arrange the same that the sand or other material may be readily guided to and discharged into the receptacle therefor.

To the accomplishment of the above the invention consists of certain novel devices and combination of devices, as will be described and claimed.

In the accompanying drawings, Figure 1 is a front view of atower with myimprovements attached, parts being broken away; Fig. 2, a vertical section of the same; Fig. 3, a detail, on an enlarged scale, of the spout and valve; Fig. 4, an enlarged sectional view of parts, the tower being omitted; and Fig. 5, a detail perspective of the valve.

Like letters refer to like parts in each view.

A represents a tower of any well-known construction, provided at a suitable point with the opening a, through which communication is formed between its interior and the chute B, which is suitably secured to the outer wall of the tower.

As shown clearly in Fig. 2, the outer lower end of chute B is contracted, and fitted upon said chute, at asuitable pointabovc its end, is a bill-shaped hood, B. Through the sides of such hood, having bearing at one end therein, and at their opposite ends in the sides of the chute, are two short shaftsb b. (Clearly shown in Fig. 4.) Suspended uponthese shafts is the valve 0, which, as is clearly shown in Fig. 5, consists of a trough shaped device, the upwardly-extending arms or ends of which are perforated for the passage of the shafts b b. One of these end pieces occupies a position upon each side of the chute, and the valve properis entirely clear of the said chute,so that the valve will not be readily worn. Upon the shaft I) there is formed a cra11k-arn1,b",to which a rod or cord, 1), is attached, and through the medium of which parts the valve is operated. Upon the rear face of the chute, at a point near its lower end, there is formed a lug, c, to which a pin or stud, d, is secured, said pin occupying a vertical position, and adapted to pass down through an opening formed near the rear edge of a piece, D. (Shown clearly in Fig. 3.) After piece D has been thus mounted on pin (Z, a nut, e, is secured upon the lower end of said pin to hold said piece in position on the pin, and at the same time allow of its being revolved. Formed upon the lower face of piece D is an extension, f, open at its front and adapted to fit into the enlarged upper end of the discharge-spout E.

As shown in Fig. 3, suitable pins or screws, 9, are passed through the sides of the spout E, near its upper edge, and also through the sides of extensionf, to hold such parts in position.

Ereprescnts a spout which is telescoped upon spout E, the same being provided at its upper end with a ring, it, and the spout E, with a similar ring, h, near its lower end to prevent the separation of the two.

The operation and manner of usingis as follows: The normal position of the parts when not in use is shown in full lines in Fig. 2. If, new, it is desired to discharge the sand into any receptacle, the mouth of spout E is inserted into said receptacle, being pulled out as far as is necessary and elevated sufficiently to form communication between spout E and the opening in extension f, as shown in dotted lines. The rope I) is then pulled, and through the medium of crank-arm I) the valve 0 is turned and carried away from the mouth of chute B, thus allowing the sand to pass from said chute to the discharge-spout. \Vhen sufficient has been fed to the receptacle, the tension is removed from the rope, and the valve will return to its normal position to close the chute by gravity,and the valve, being entirely 9 5 and pin d, of valve 0, revolving piece D, and discharge-spout E, as set forth.

In testimony whereofI affix my signature in presence of two witnesses.
